FoIP (Fax-over-IP)

FoIP (Fax over Internet Protocol), is a software-based technology that changes the way a fax is transmitted, similarly to the way VoIP (Voice over Internet Protocol) changes how a phone call is transmitted. Instead of the fax being sent directly over the PSTN (public switch telephone network), the data is sent over the IP network, avoiding the long-distance phone lines of the PSTN. By initially bypassing the PSTN, the cost of transmission is often reduced and makes for a more efficient setup for businesses that already have access to the internet.

FoIP is the future of how people send and receive faxes because it can complement and leverage your IP network, eliminating the need for traditional fax boards. With FoIP, your organization can expect all the advantages, reliability, and security of a traditional fax server solution, but with added benefits, such as server consolidation through virtualization and a unified communications strategy that is inclusive of fax. And, with the proliferation of SIP Trunking (we recommend babyTEL), you can truly leverage FoIP by sending faxes over the internet.

How does FoIP Work?

RightFax communicates via FoIP through Dialogic Brooktrout SR140 software which is included on a RightFax FoIP enabled channel. Brooktrout SR140 is a board-less, host-based FoIP engine that leverages existing field-proven Dialogic Brooktrout fax technology to deliver high levels of performance, reliability, and scalability using multiple communication options, including G.711, T.38, SIP and H.323.

Once the call is set up, the fax payload is transmitted via T.38 (recommended) between the fax server, the communication device, and the end point. The end point may be a fax server or a classic fax machine. In the case of a media gateway, the gateway is responsible for connecting the call to the traditional Public Switched Telephone Network (PSTN) and completing the path to the receiving device. Typically these devices are part of a larger VoIP/FoIP infrastructure providing voice, fax, email, and messaging.
